Dolby Surround Upmixer - Pioneer Elite SC-89 Operating Instructions Manual

5. Dolby Surround Upmixer

Clients that invest in a Dolby Atmos home theater naturally expect to get full use of
all of their components, even when the content they are playing isn't mixed in Dolby
Atmos. This includes taking advantage of overhead and Dolby Atmos enabled
speakers to further enhance the playback experience.
Included in the Dolby Atmos technology bundle is a new, advanced upmixer designed
to be compatible with traditional channel-based as well as Dolby Atmos speaker
systems. The Dolby surround upmixer expands the audio of legacy channel-based
content, including native stereo, 5.1, and 7.1 content, for playback through a Dolby
Atmos system—regardless of speaker number or placement—while simultaneously
honoring and maintaining the artists' intent for the mix.
The Dolby surround upmixer analyzes and processes multiple perceptually spaced
frequency bands, accurately steering each individually. The result is a surround
playback experience characterized by precisely located audio elements and a more
spacious ambience.
In a Dolby Atmos system, the channel-based mix is fully honored. Dolby Atmos
enabled speakers and overhead speakers are employed to lend a sense of
atmospherics or room effect to the listening experience. This new technology will
process and upmix channel-based content to as many as 17 speaker locations at
listener level and 10 Dolby Atmos enabled or overhead speakers. Note: To maintain
an accurate frontal audio image, the upmixer will not send upmixed audio to the
front wide speakers or any speakers that are located between the Left, Center, and
Right speakers. Audio is not upmixed to the Center Surround speaker.
A Center spread on/off control enables the user to spread the center image across a
wider front soundstage. This optional feature is ideally suited for playback of two-
channel music content or playback of channel-based content in a home theater
design that employs a wider screen configuration than typical installations.
The Dolby surround and center spread function should be selected from the AVR or
pre-processor user interface or from the system's remote control.
